Fisherr V260 Ball Control Valve
The Fisher V260 is a full-bore control valve designed
from the ground up with features for optimized
pressure, flow and process control. An integral drilled
attenuator controls noise and vibration from high
pressure drop liquids and gases. The splined shaft
connection to the actuator reduces lost motion.
The V260A with Aerodome attenuator, V260B with
Hydrodome attenuator, and V260C Ball Control Valves
(figures 1 and 3) combine the efficiency of a rotary
valve with the energy-dissipating capability of a special
trim to provide improved performance for demanding
applications. The valve is available with single, dual, or
dual block-and-bleed seal options (see the
Specifications table).
The trim design of the V260A is used in gas service to
reduce noise effects that cause pipeline vibration. The
V260B provides improved performance for demanding
applications such as pump bypass and pipeline
take-off. The trim is designed for liquid service to help
eliminate or reduce cavitation and associated pipeline
noise and vibration. The V260C full-bore ball valve is
designed for automated control in bypass, batch,
monitor, and emergency shutoff service applications,
and it presents little or no restriction to flow.

Aerodynamic Performance-- Up to -20 dBA
acoustical attenuation can be achieved for the
V260A within a single stage construction.
Dual-stage construction can provide up to -25 dBA
attenuation.

Improved Service Life-- The attenuator is not part of
the seal assembly. The seal wipes to ball surface, not
the attenuator, promoting increased service life.

Trim Versatility-- Key valve components, such as
valve body, ball, shaft and bearings, are
interchangeable between the V260A, V260B and
V260C. This feature allows you to reduce your spare
parts inventory and maintenance time.

The V260 full-bore ball valve is available with
composition seals, and process type stem packing for
improved service life.
Unless otherwise noted, all NACE references are to
NACE MR0175-2002.

Features

Excellent Flow Control-- The splined ball to shaft
connection, splined shaft to actuator connection,
double power-end bushing assemblies, and
trunnion guiding, all provide improved dynamic
control.
